용융 흐름 지수 폴리머
Melt Flow Index Testing Equipment
Function and usage
To test the melt flow rate (MFR, 단위: g / 10 분) 고온의 열가소성 소재, 예컨대 폴리에틸렌, 폴리스티렌, 폴리 프로필렌, ABS 수지, 아세탈 수지, 폴리카보네이트, 나일론, 불소수지 등, 플라스틱 재료 산업에서 널리 사용됩니다., 플라스틱 제품, 석유, 화학, 연구소, 검사기관 등.
기준:
GB/T9643, GB/T3682, JB/T5456, ISO1133
Working principle:
GBB-R Melt Flow Indexer makes the test material reach molten state at a prescribed temperature in the high-temperature furnace. Such melt test material goes through a small hole of specific diameter at a normative load, subjected to extrusion test. In the production of plastics, MFI is usually used to indicate the fluidity, viscosity and other physical properties of polymers. Melt flow rate is expressed in the weight or volume of polymer per 10 minutes of the test or the average weight of each extruded material.
응용 프로그램:
Thermoplastic materials such as polyethylene, 폴리스티렌, 폴리 프로필렌, ABS 수지, 폴리카보네이트, 나일론, fluoroplastic and etc.
